CAS 9002-92-0 generally identifies polyoxyethylene lauryl ether, a nonionic surfactant made by adding ethylene oxide units to a lauryl alcohol-derived hydrophobe. I use this material when a formulation needs wetting, emulsification, detergency, or compatibility across a broad range of ionic conditions. Because the CAS number can cover products with different average ethoxylation levels and commercial specifications, I recommend confirming the product grade, average EO number, HLB value, appearance, water content, and performance data before purchasing.
This guide explains the identity, properties, common uses, selection factors, handling considerations, and supplier questions that matter when sourcing CAS 9002-92-0. It is intended for formulators, procurement teams, distributors, and manufacturers evaluating nonionic surfactants for industrial or consumer-product applications.
CAS 9002-92-0 is commonly used for polyoxyethylene lauryl ether, also described as a polyethylene glycol monododecyl ether family. Its basic structure combines a lauryl hydrophobic group containing 12 carbon atoms with one or more ethylene oxide units that provide hydrophilic character. The exact commercial behavior is therefore not determined by the CAS number alone; the average number of ethylene oxide units and the distribution of molecular species are important.
Unlike anionic surfactants, nonionic surfactants do not carry a permanent electrical charge in water. This can make CAS 9002-92-0 useful in formulations containing salts, other surfactants, pigments, oils, or active ingredients that may interact with charged materials. However, compatibility still needs to be checked experimentally because concentration, temperature, hardness, solvent choice, and formulation pH can change the final result.
The most important selection factor is often the hydrophilic-lipophilic balance, or HLB. A lower ethoxylation level generally gives a more oil-compatible material, while a higher ethoxylation level generally increases water affinity, but this relationship should be confirmed using the supplier’s measured or calculated product data. Buyers should not assume that every product sold under CAS 9002-92-0 has the same HLB or the same emulsion behavior.
Commercial polyoxyethylene lauryl ether grades may be supplied as liquids, pastes, or waxy solids depending on their average ethoxylation level and product design. Appearance, pour point, melting or softening range, cloud point, viscosity, and water content can affect processing and storage. A supplier should provide the actual specification for the selected grade instead of relying only on a general CAS description.
| Specification or test | Why it matters |
|---|---|
| Average ethoxylation level | Helps predict water affinity, detergency, and emulsion behavior. |
| HLB or equivalent product guidance | Supports selection for oil-in-water or water-in-oil systems. |
| Active content and water content | Allows accurate formulation calculations and batch comparison. |
| Cloud point and viscosity | Helps assess temperature sensitivity and manufacturing requirements. |
| Color, odor, and acid value | Useful for appearance control, odor-sensitive products, and quality release. |
CAS 9002-92-0 can act as a wetting and detergency aid in cleaning systems. Its nonionic character may help remove oily soils while working alongside anionic, amphoteric, or other nonionic surfactants. The suitable dosage is formulation-specific, so I recommend beginning with controlled laboratory screening rather than transferring a generic concentration directly into production.
The material can support the formation and stabilization of emulsions containing water and hydrophobic components. It may be considered for industrial cleaners, metalworking-related formulations, textile auxiliaries, agricultural formulation components, and other systems where controlled interfacial activity is required. The final choice should be based on emulsion type, required storage stability, shear conditions, and the compatibility of the surfactant with oils, solvents, polymers, and preservatives.
Polyoxyethylene lauryl ether may improve the wetting of powders, surfaces, fibers, or hydrophobic particles. This function can be valuable when a formulation has poor spreading, slow incorporation, or inconsistent contact with a substrate. It should not automatically be treated as a complete dispersant, because pigment stabilization and long-term dispersion may require a polymeric dispersant or a tailored surfactant blend.
I begin by defining the formulation problem rather than selecting a product only by CAS number. The key questions are whether the system is water-based or oil-based, whether the target is wetting or emulsification, what temperature range is used, and whether the product must meet specific regulatory or end-use requirements. I then compare the supplier’s technical data with a small-scale compatibility test.

I treat CAS 9002-92-0 as an industrial chemical that requires the supplier’s current safety data sheet and site-specific risk assessment. Recommended personal protective equipment, ventilation, spill response, and storage conditions should follow the applicable SDS and local workplace procedures. The appearance of a material can change with temperature, so storage and transfer conditions should be checked against the grade-specific documentation.
Common mistakes include assuming that all polyoxyethylene lauryl ether grades are interchangeable, ignoring cloud-point behavior, and approving a material without checking water content or active concentration. Another frequent error is evaluating only initial emulsion appearance while failing to test separation after storage or temperature cycling. I also recommend checking whether the intended end use has additional requirements for impurities, allergens, biodegradability, labeling, or restricted substances.
A qualified supplier should be able to identify the commercial grade clearly and explain how it relates to CAS 9002-92-0. I would request a technical data sheet, safety data sheet, certificate of analysis format, typical specification range, packaging details, shelf-life information, and sample availability. If the material is intended for export, the buyer should also confirm labeling, transport classification, customs documents, and destination-market requirements.
The price of CAS 9002-92-0 depends on grade, ethoxylation profile, active content, packaging, order volume, origin, freight, and market conditions. A low quoted price may not represent a lower total cost if the product has inconsistent viscosity, higher water content, unsuitable packaging, or poor application performance. I recommend comparing quotations on a delivered-cost and specification-equivalent basis.
MOQ and lead time are also grade-specific. Standard grades may be easier to schedule, while customized specifications or special packaging can require additional production planning. Before issuing a purchase order, confirm the quoted validity period, production lead time, available stock, packing unit, loading quantity, and procedure for handling nonconforming material.
As a supplier serving the Alcohol, Hydroxybenzene, and Ether sector, Yuking can help buyers organize the technical information needed to evaluate CAS 9002-92-0. Our support should begin with clarifying the intended application, required physical form, target specification, packaging preference, destination, and expected purchasing volume. Based on those details, we can discuss suitable product options, sample evaluation, documentation, and export coordination without assuming that one grade fits every formulation.
For a more efficient quotation, I recommend sending the required purity or active-content range, target HLB or application function, packaging size, annual or trial quantity, destination port, and documentation requirements. If you already have a benchmark product, sharing its technical data sheet can help the supplier compare specifications more accurately. Final approval should remain based on your own formulation testing and the agreed commercial specification.
CAS 9002-92-0 is commonly associated with polyoxyethylene lauryl ether, a versatile nonionic surfactant used for wetting, detergency, emulsification, and related formulation functions. The correct grade cannot be selected from the CAS number alone because ethoxylation level, HLB, physical form, cloud point, active content, and impurity profile can vary. The most reliable path is to define the application, compare documented specifications, test a representative sample, and confirm supply conditions.
Your next step should be to prepare a short technical purchasing brief and request a matching quotation, sample, SDS, technical data sheet, and certificate of analysis format. Yuking can support this process by reviewing your application and supply requirements for CAS 9002-92-0.
